Understanding Light Dependent Resistors (LDRs) – Light Dependent Resistors and Their Practical Implementations A Photoresistor or sensor LDR is an important component commonly utilised in photo-sensitive electronic circuits. This special sensor changes its resistance based on the amount of light falling on it. When illuminated by bright light, its resistance https://essentialsystem10.tinyblogging.com/the-growing-craze-about-the-ldr-sensor-82869447
